Are you using netbeans IDE to build and deploy your application?

If you are use this link to set up connection to mysql. IS for postgre but works for mysql as well. LINK

I think that the problem is that the mysql.jar is not in the common/lib in your tomcat. copy the lib to the common/lib folder and try again.

Narasimha,

please, PLEASE!, don't post in all uppercase letters. It's considered shouting, and thus rude, all over the 'net: KeepItDown. It's also unnecessarily hard to read.
